Catchy melodic motif performed loudly by Irish men making comeback (4)
I believe the answer is:
riff
'catchy melodic motif performed' is the definition.
I can't tell whether this definition defines the answer.
'loudly by irish men making comeback' is the wordplay.
'loudly' becomes 'f' (short for forte - 'loud' in music).
'by' says to put letters next to each other.
'irish men' becomes 'fir' ('men' in Irish Gaelic).
'making comeback' says the letters should be written backwards.
'fir' back-to-front is 'rif'.
'f' after 'rif' is 'RIFF'.
Can you help me to learn more?
(Other definitions for riff that I've seen before include "Berber - repeated jazz phrase" , "Ostinato common in jazz, rock, etc" , "Short series of chords in jazz" , "bit of music" , "Moroccan - musical phrase" .)
